HOSE-CONNECTOR.

Specification of Letters Patent.

Patented Jan. 28, 1913.

Application filed June 7, 1911. Serial No. 631,863.

of Illinois, have invented certain new and useful Improvements in HoseConnectorsg and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in that class of devices known ashose connectors or hose menders used for connecting or joining the endsof hose sections.

It also relates to a connector or mender tor connecting the ends of abroken hose in an absolutely permanent manner. Also to means forattaching a hose to a hose-coupling such as is used for connectinghosescctions, or for coupling a hose to a faucet, hydrant, pipe or otherpart or fixture.

An object of the invention is to provide a connector for hose sectionsby which said sections can be permanently or inseparably connected.

Another object is to provide a device for a hose fitting which willsecure the hose to said fitting in an absolutely permanent manner or soas to render the hose and the fitting inseparable.

All the above are accomplished by the use of a combination of parts newin the art.

The invention, besides the foregoing, relates to certain details'ofconstruction for bringing about certain desired definite results all ofwhich will appear in the following specification aided by theaccompanying drawing in which:

Figure 1 is a longitudinal section of a hose connector. Fig. 2 is a faceview of a hose-engaging member provided With a series of radiatingfingers. Fig. 3 is a second hose-engaging member also provided with aseries of fingers. Fig. 4 is a third hose-engaging member similar tothat in Fig. 2. Fig. 5 shows the connector completely assembled. Fig. 6is a side elevation of a hose-fitting showing a portion of a hose inconnection therewith. Fig. 7 shows another form of fitting. Fig. 8 showsthe fitting illustrated in Fig. 6 with its parts in the hose holdingposition. I

Before proceeding with the description of the invention in detail it isto be stated that the purpose of the structure is to provide a form ofconnector or mender somewhat difterent from and having certainadvantages over that shown in my former Patent No. 946,703, issuedJanuary 18,1910, by providing three hose-engaging members, instead oftwo, for clamping the hose. In this patent the two hose-engaging membersare mounted upon a tubular hose-receiving part and each engages aseparate hose-end, while in the device to be described, in place of thetwo members mentioned, two members of a different kind are used togetherwith a third hose-holding member, all three of the members being forcedinto engagement with the said hose-ends. This has been stated. in orderthat. the differences in structure will be readily apparent, while theadvantages of the new form will appear as the description proceeds.

A indicates a tube preferably of a ductile metal forming a connectingmember for the hoseends and upon which the said ends to be joined areplaced,-these being indicated at a a. This tubularmember A is providedwith an enlargement or head B at each end by expanding the metal in anysuitable manner.

C, E and D represent three hose-enga 'ng members which may be designatedas rst, second and third respectively. They are all made of sheet metal,the first having a central hole C and provided with a series of spacedradiating fingers C and, in addition, it is preferably provided with anannular flange C formed up from the metal around the hole C althoughthis flange may not be used. The second member E is a duplicate of thefirst in having a central opening E and the radiating spaced fingers EIt may also have a flange E", if desired, to correspond with Cdescribed. The third member D is provided with a correspondingcentralopening -D' and a series of radiating fingers D thesesaid fingers beinggreater in number than the numher on either of the members C and Edescribed and this said member preferably does not have a flangesurrounding its central opening, being merely a flat plate. The threemembers are slipped upon the tube A before the heads B B are formed,their bores being but slightly larger than the diameter of the tube orsuch that they can be 1 readily slipped upon it. The relation of therings one to another is-clearly shown in Fig. 1 wherein, for instance,the members C and E are placed with their flat sides facing one anotheror with the flanges C and E facing in opposite directions. The member 'Dis secured between the inner facing surfaces of the members C, E, andall of the parts may be secured together upon the tube A by any goodmeans. Preferably I provide for this purpose an enlargement F at eachside of the position of the parts by expanding the tube so as to make itof larger diameter than that portion upon which the members are retainedand these enlargements serve to prevent movement of the membersrelatively and also prevent their rotation upon the tube or shiftingmovement along it in a longitudinal direction. While it is not new toemploy enlargements to hold hose engaging members in position there is aparticular advantage in the form of such enlargements in the presentmender, but this will appear later.

It is observed that the members C and E in the present instance areshown with five fingers each, though a greater or less number may beused, and also that when secured in position upon the tube A the fingersof one member lie' opposite the spaces between the fingers of the othermember, as indicated by broken lines in Fig. 4, and the fingers of eachmember are bent outward in opposite directions as clearly shown in Figs.1 and 5. The central or third member D as shown in Fig. 3, has twice asmany fingers as either of the members C, E, but a less number may beused and will be shown pres ently, and when in position one of itsfingers, in t-he present instance, lies opposite each of the fingers ofboth those members. Since the fingers C and E are spaced apart theopenspaces between them are filled by the fingers of the middle member.As all of the fingers of one of the members are bent in a, directionoppositethose of the other, the fingers of the third or central member Dcan be bent alternately in opposite directions; one of them lying withineach of the said spaces between the said fingers C and E, as indicatedin Fig. 5 by the several reference characters, and the ends of thefingers of said third member are provided with spurs D to obtain a firmhold upon the hose. Preferably the. fingers of the three members are allof such a width that when all are bent down upon and in engagement withthe hose as indicated, for instance. in one of the forms of fittings inFig. -8, they will constitute practically a continuous band around thehose since their edges will practically abut. mer patent referred towherein two members corresponding to C E herein are employed, thefingers of which adjoin at their bases, those in the present instanceare spaced apart and permit the fingers of the third member D to lie inthe resulting spaces for the special purpose of engaging both thehose-ends. This structure and arrangement prevents said hose-end from.rotating upon the member A, should the members C E be loose, and alsosince both the hose-ends are held by the one member D they cannotreadily be drawn apart as may result when a single member C E engagesthem, since in dragging the hose over the ground or otherwise subjectingit to great strain one or the other of the members C E, may leave itsposition should the enlargement F be improperly formed. The ends of allof the fingers of the three members when bent down terminate just behindthe heads B so that the hose is forced down and held behind said headand aid in preventing the hose being separated from the connector.

The enlargements F as before stated are greater in diameter than theinterior diameter of the hose so that when the latter is forced uponthem it is distended and made of larger diameter thereby causing it tobe stretched upon said enlargement to further aid in preventing leakagearound it.

I have stated that a greater or less number of fingers C and E can beemployed this being elective. It has been said, also. that a less numberof fingers D can be used than shown. A reduction in number is possibleand such of said fingers D as may be employed may lie opposite thespaces between the fingers of the members C E as shown and as beforedescribed, or they may overlie said fingers or lie opposite both thefingers and the spaces, but this all lies within the meaning of myinvention.

Returning now to the consideration of the peculiar form of theenlargement F, used in the several forms herein, it is to be said thateach said enlargement, together with the flanges C and E constitutespractically a continuous straight surface from a point behind the headsB to the rings C E and of a diameter larger than the interior diameterof the hose. When the hose-end is forced over the head B it is distendedand kept so for the distance it overlies the said enlargement and theflange of the adjacent ring. Now, when the fingers of the ring are bentdown flatupon the hose they clamp it upon the described parts besidesforcing it behind the head B. Thus the chance for leakage is very remoteand much more so than where a mere annular rib or flange is employed,because the adjoining surfaces of the fingers and the enlargement clampthe hose between As distinguished from my for- 1 them for a considerabledistance. This distinguishes the present device from that of 3 my issuedpatent referred to in this respect. This feature, together with thethird or m1ddle ring D constitute important parts of my 1 invention.

hose-engaging members in connection with fittings of the male and femalethreaded end may be clamped or secured to the structure in some othersuitable manner.

In Figs. 6, 7 and S I have illustrated the ing a hose end. or this lastmentioned hose type for attaching hose sections to one another or forattaching a section to a hydrant. faucet. sprinkling device or the like.the first of the figures G indicates a threaded male fitting having aflange H against which the end of a female member J. Fig. 7. may abut.Upon the stem K of the fitting G behind and bearing against the saidflange H is a member L corresponding to the member D, before described.

the stem K is enlarged at N for securing the members L M in place andthe free or outer extremity of the stem has ahead 0 over which the hoseis forced. \Vhen the latter is in position the two series of fingers L Mof the members L and M respectively. which series may both be equal innumber, are forced down upon it. those of one or the other of themhaving spurs bent down if desired to better engage the hose. but. ifdesired, the fingers of both the members may be'provided with these saidspurs. The construction of the female fitting in Fig. 7 is identicalwith that just described and in Fig. 8 the fingers of the members areshown in their hose engaging positions it being understood that thefingers M lie in the spaces between the fingers L' as in the formerinstance.

I may not employ the flanges of the members C, E and M but merely usethe flat metal parts and in this event the enlargements F would, ofcourse, extend closer to the middle of the member A to properly holdsaid members. It is preferable. however, to employ said flanges since bythat means the device is stronger and there would be no possibility ofthe members rocking or tilting upon the said member A.

An advantage in the particular form of the members C E and the othershaving spaced fingers, is that the dies for making the same can be moreeasily made since in widely separating or spacing the fingers theportion of the dies need not be made with such sharp angles or pointsand they are therefore not as easily damaged. The fingers of one memberlie in the spaces between the fingers of the other. and their edges abutthereby producing the same result as that obtained by fingers whichdirectly adjoin at their bases. For instance. ring D may cooperate withring E, when the alternate fingers D of the former will lie opposite thespaces between the fingers 3 of the latter and are adapted to be bentdown between them, while the other set of alternate fingers of ring Dextend in th Adjacent this member L is a member M which is identicalwith one of the members C E of the other t form described and as in saidother form figures of the drawing that the ring 1), twlllPll is themiddle one, may cooperate with only one of the rings C E which wouldform an operable con'ibination, together with the tubular member.

Slight changes. of course, may be made in the device such as will fairlyfall within the meaning of the invention.
